To all whom *itmay concern:

Be it known that we, HARRY ADELsoN and CLARK W. BLIss, citizens of theUnited States, residing at Cleveland and Lakewood, respectively, in thecounty of Cuyahoga and tate of Ohio,have invented certain new and usefulImprovements in Liquid-Measuring Devices; and We do declare that thefolloz: ing is a full, clear, and exact description of the invention,which v. ill enableothers skilled in.

the art to which it appertainsgtoniake and use the same. I

a Our invention relates to liquid measuring devices, and the'inventionis embodied in a division of our application for LettersPatent dated AugustlO, 1907, Ser. No. 387,959..

In the accompanying drawings, Figure 1 is a side elevation of a liquidmeasuring apparatus comprising our invention within the same, and Fig. 2is a vertical sectional elevation of one of the measuring units orreceptacles employedin said apparatus and considerably enlarged. Fig. 3is across section on line 33, Fig. 2, looking dotvn.

The invention as thus illustrated covers substantially the sameconstruction as is shown in Fig. 7 in the above entitled application butisnot specifically claimed therein, another construction of valvemechanism being specifically claimed in said case. The

present invention is, therefore, confined more particularly to the partsarranged and adapted to operate substantially as shown .and comprises avessel or receptacle V, one or more, and usually a series of suchvessels are employed and operatedtogetherin tank T an operativelyconnected with cover O, or equivalent part, free upon saiditank to beraised and lowered. For this purpose, as in said other application, Weemploy opposite side frames F, which carry cover 0 and are raised andlowered by toggle links L, connecting piece P and handle or lever H. Theforegoing or other operating mechanism may be employed for the valvecontrolling sleeve S and rod R and associated mechanism, the sleeve Sbearing against part 0 from beneath and rod R extending through part 0and having adjusting nuts 2 on its upper end adapted to give more orless play to said part or cover C before it engages said nuts andraisesvalve 3, which is fixed to the lower end of saidrod. Neither rodIt nor sleeve S is fixed to cover C, and sleeve S is sustained againstthe bottom of part O by spring l'beneaththe same about rod R and bearingat its lower portion on ball valve 3. A suitable guide 5 on sleeve Ssupports said sleeve in a central position in vessel V...

The valve 3 controls the exhaust or outlet from the measuring vessel,and ball valve 6 controls the inlet or supply opening 7 for liquid tofill said vessel from the interior of tank T.. The said ball or valve 6.is free in a cage to rise and fall as to seat 7, which is in the top ofa side extension 8 formed integral with vessel V, in this instance, andconstituting a part of the measuring space of the vessel. An arm orlever 9 is pivoted between its ends in said side extension or space andhas an upwardly extending end adapted to engage beneath ball 6 and raisethe ball from its seat to. admit liquid into the vessel, and said leveris bifurcated at its other end and engaged about rod It and spring 4directly beneath the flange d at the lower end of sleeve S. It followsthat when cover 0 is lowered it will depress sleeve S against itssustaining spring 4 and bearing upon the end of lever 9 v.-ill raisevalve 6, but not before valve 3 has been depressed to its seat 1.0, ashereinafter more fully described. Vessel V has an externally threadedextension 12 at its bottom Which seats snugly in a correspondingopeningin the bottom of tank T and said extension is engaged by a ringnut 14 about its side next beneath said bottom, thus firmly fixing thesaid vessel in said tank with its valve seat 10 outside and beneath thetank. I

In operation the positions of the valves 3 and 6 are determined bytheposition of cover 0 through lever H and intermediate parts controllingsaidcover, and the measuring I Fig. 2 and valve 3 is closed and valve 6open.

Then When the said vessel has been discharged the cover C iscorrespondingly raised and valve 3 opened and valve 6 closed. But thereis enough play in rod R over the cover and beneath nuts 2 to permitsleeve S to rise and valve 6 to seat before valve 3 opens, thus closingoff the inflow of fluid While discharging takes place. After themeasuring vessel has emptied the positions of the valves are reversedand valve 3 closed before valve 6 opens, and so on alternately. Thefluid level in the tank is automatically maintained, as described in theoriginal apl plication, and is the same for all vessels in the tank.Then When the said vessel is to be discharged the cover C is raisedagainst nuts 2 on rod R and outlet valve 3 is opened, but this does notoccur before spring 4 has raised sleeve S, as cover C rises and inletvalve is permitted to close through the changed position of lever 9.Thus valve 6 really closes before valve 3 opens though the operation ofboth valves is a single operation in fact and their seating andunseating or raising is successive and alternate. Valve 3 will in likemanner be closed just before valve 6 is opened in a reverse operation ofparts, and so on, all the operating parts for all the vessels in tank Tworking simulta neously.

Valve 6 is preferably provided u ith a stem 20 sleeved through a sidesupporting arm 22 on vessel V, and a spring 21 arranged between the saidarm and valve 6 serves to press and hold the valve to its seat 7 exceptwhen raised by lever 9.

What we claim is:

1 A tank adapted to contain liquid, a liquid measuring vessel seated insaid tank having an offset at its bottom provided with an inlet openingfor liquid to said vessel and an exhaust opening in the bottom of saidvessel through the bottom of the tank, valves for said openings andmeans to open and close said valves in a single operation comprising arod controlling said exhaust valve, a sleeve on said rod, levermechanism in operative relation with said sleeve adapted to open saidinlet valve, and separate means engaging the upper end of said rod tocontrol said exhaust valve.

2. A liquid measuring tank, a liquid measuring vessel removably seatedin the bottom thereof having inlet and exhaust openings at its bottom ondifferent horizontal planes, a separate valve forea'ch opening and meansto open and close said valves alternately comprising a rod carrying theexhaust valve and a pivoted lever operatively related at one end withsaid inlet valve, and means on said rod adapted to operate said lever.

3. A measuring vessel for liquid having an exhaust opening in its bottomand a side extension at its bottom with an opening in its top to admitliquid, a valve for each opening and connections for operating saidvalves conjointly comprising a rod carrying said exhaust valve and alever supported in lifting relation to said inlet valve, a sleeveslidably mounted on said rod and engaging said lever and a spring toraise said sleeve, and means at the top of said rod and sleeve tooperate both rod and sleeve.

4. The measuring vessel having an exhaust valve seated in the bottomthereof, and a rod on which said valve is mounted, a sleeve about saidrod and a spiral spring on the rod between said sleeve and valve, incombination with an inlet valve at one side of and on a plane above saidexhaust valve, and a seat therefor, a pivotally supported lever adaptedto open said inlet valve and operatively connected with said sleeve, andmeans at the upper ends of said sleeve and rod to raise and lower thesame and thereby control said valves.

5. A measuring vessel for liquid open at its top and ada )ted to befilled to a predetermined level beneath its top and having an exhaustopening directly in its bottom and an inlet opening at its side abovethe plane of said exhaust, in combination with a valve for each openingand means to operate said valves together comprising a rod carrying eachof said valves, a sleeve about said rod, a spiral spring about said rodbetween said sleeve and said exhaust valve, means between the upper endof said rod and sleeve to raise and lower the same and a lever tooperate said inlet valve having working relation with said sleeve.

In testimony whereof we sign this specilication in the presence of twowitnesses.
